| 摘 要： | 由于预报模型的局限性和实时信息的不完善,洪水预报过程存在许多误差,而基于图形交互式修正技术是消除预报误差的有效手段。分析了水文预报过程交互式修正技术在洪水预报工作中的重要性,介绍了过程拟合平滑技术和样条插值技术,基于此基础上研究实现了以橡皮筋形式交互式修正水文预报过程的技术,并应用于洪水预报系统中。研究实例表明,该技术使用方便,有效地提高了洪水预报精度。

| Abstract: | There is much error in flood forecasting process due to the limited model and the inadequate real-time information,however,it is an effective method based on the hydrograph interactive technology to reduce the forecasting error.This paper introduces the significance of the interactive correct technology applied to forecasting hydrograph,and the process-fit-smoothness and the cubic interpolation technology.Based on the technology above,it can be realized to correct the forecasting hydrograph interactively in the form of elastic which is applied to the flood forecasting system.The case study indicates that the technology can be used easily to improve effectively the accuracy of flood forecasting. |
